SPECIFICATION formingpart of Letters Patent No. 763,891, dated June 28,1904.

Application filed August 22, 1903.

To all whmn it nuty concern:

Be it known that 1, CHARLES HESSE, a citizen of the United States,residing at Red bluff, in the county of Tehama and State of California,have invented new and useful Improvements in Harvesters, of which thefollowing is a specification.

My invention relates to new and useful im provements in harvesters; andits object is to provide a grain-saving attachment by means of which anygrain which may be discharged with the straw and chaff will be recoveredand refed to the cleaning mechanism of the harvester and ready forsacking.

With the above and other objects in view the invention consists in thenovel construction and combination of parts hereinafter more fullydescribed and claimed, and illustrated in the accompanying drawings,showing the preferred form of my invention, and in which Figure 1 is aside elevation of the rear portion of a harvester having my improvedattachment used in connection therewith and showing in dotted lines thechains and belts arranged ateither side ofthe machine. Fig. 2 is asection through the casings of the elevators of the attachment andhaving one portion of the side broken away to show themechanism'contained therein, and Fig. 3 is a horizontal section showingin plan the worms and fan of the apparatus.

Referring to the figures by numerals of reference, 1 is the casing of aharvester having the ordinary main carrier 2 arranged at one sidethereof and connected to the end of a shaft 3, with which rotates a worm4, extending transversely of the casing adjacent the main shoe. (Notshown.) A straw-carrier is located within the casing 1, near the upperportion thereof, and is adapted to conduct the straw to an outlet .6.The parts herein described are those employed in harvesters of theordinary construction. My invention consists of certain additional partsadapted to be used in connection therewith. It comprises a tailer orconveyer 7 which is arranged within the casing 1 at a point above theworm 4 and the main shoe, and this tailer is mounted on shafts 8 and 9,one of which,

Serial No. 170,481. (No model.)

9, is provided with asprocket 10, upon which is arranged a chain 11,which extends over 'a sprocket 12, connected to one shaft, 13, of thestraw-carrier 5. This straw-carrier receives its power from its othershaft, 14, which is arranged at the opposite end thereof.

Sprockets are fastened in any suitable manner to a power-shaft 16, and ashaft 17 is journaled upon the casing 1, and pulleys 18 and a sprocket19 are connected thereto. A chain 20 is utilized for transmitting motionfrom one of the sprockets 15 to the sprocket 19, and another chain 21connects a sprocket 15 with a sprocket 22, connected to the shaft 3 ofthe worm 4.

An eccentric 23 is arranged within the easing 1 and is connected to oneend of a screen 24 and is adapted when rotated to impart a reciprocatingmotion to said screen. This eccentric has a pulley 25 connectedthereto,which is driven by a belt 26, arranged on one of the pulleys 18.An inclined board 27 is arranged under screen 24, and at its upper endis an outlet-opening 28. A channel 29 is formed within this inclinedboard and extends transversely thereof, and within the channel isrevolubly mounted a worm 30, having a sprocket 31 upon one end thereof,which is connected by a chain 32 with the sprocket 10, hereinbeforereferred to. A conveyer or elevator 33 extends upward from one end ofthe channel 29 and is inclosed by a casing 34, having an outlet 35,through which material carried by the elevator is adapted to bedischarged upon an inclined board 36, which extends downward into anaperture 37 formed in the top of the casing 38 of the main carrier 2. Afan 39 extends transversely of the casing 1, between theworms and 4, andis adapted to direct a blast of air along the inclined board 27, so asto drive all chaff and other extremely light particles dischargedthrough the screen 24 outward through the aperture 28. The shaft 40 ofthis fan 39 has a pulley 41 thereon, to which rotary motion istransmitted from one of the pulleys 18 by acrossed belt 42.

The operation of the apparatus is as follows: The grain and chaff isdirected from the main shoe of the machine to the tailer or conveyer 7and is conducted thereby upward upon the screen 24;. The arrangement ofbelts, chains, and pulleys will, as is obvious, cause the eccentric 23to rotate when the power-shaft 16 is revolved, and a reciprocatingmotion is thus transmitted to said screen, and the chaif and graindeposited upon it is caused to drop therethrough and upon the inclinedboard 27. This board will direct it to the channel 29, where it will begathered by the worm 30 and carried to the conveyer 33. This conveyerwill draw the material upward to the outlet 35 of the casing 34, fromwhich it will be discharged to the board 36 and into casing 38. The maincarrier 2 within this casing will conduct the grain back to the machine,where it can be cleaned and sacked, as ordinarily. The fan 39 will, asis obvious, be rotated by belt 42 and will blow through the outlet 28all chafi falling from the screen 24.

By providing an attachment such as herein described a large saving ofgrain is made without adding materially to the cost of the machine orthe power required to operate it.

In the foregoing description I have shown the preferred form of myinvention; but I do not limit myself thereto, as I am aware thatmodifications may be made therein without departing from the spirit orsacrificing any of the advantages thereof, and I therefore reserve theright to make such changes as fairly fall within the scope of myinvention.

Having thus described the invention, What is claimed as new is Thecombination with a harvester having an apertured casing, a main carrier,and a casing inclosing the carrier and having an inlet; of a conveyerwithin the first-mentioned casing and at one side of the main carrier, areciprocating screen adapted to be fed by the conveyer, an inclinedboard under the screen, said screen and board extending from theaperture in the harvester-casing, a fan adapted to direct an air-currentalong the board and through the aperture, a revoluble worm Within achannel extending transversely of the board and out of the path of theair-current, an elevator extending from and operated by the Worm, and aninclined board for directing material from the elevator to the inlet inthe casing of the main carrier.

In testimony whereof I aflix my signature in presence of two witnesses.

CHARLES I-IESSE.
